To all whom it may concern: l

' and CAMILLE RoDniGUEs-ELY', citizens of France, residing at Paris,'in the Republic of France, have. invented certain new anduseiulgrnproveinents in A paratus for Perio- 'rajting and Cutting Meta s, of which .the following is a full, clear, andv exact description.`

. The subject ot-the present invention is a device for cutting and peri'orating metalsfby means of a stream of gas'u'nder pressure.

The process to Which the apparatus relates consists in leading the combustible, serving to heat the place of vwork in a plurality of streams-to the place of Work.

the'oxidizing gas, so that the two kinds" oi gas (combustible and oxygen) serving to out or perforate the metal combined in large aros on the piece of Work, Vith the apparams-constituting thepresent invention on the other hand, the quantities of gas necessary for the heating' is lead in several independent sjtreai'iis/to the work for the purpose of in creasingitliproduction of heat, and to bring about 'a niore intense heating ot' the l piece of Work.

A further novel featureof the present in.- vention consists in arranging the outlets for the gas and combustible 'in different places or v'in arranging the outlet for the current oi gas as near as possible to the place ot Work. This division of the current of gas has the great advantage that its leading can be regulated according tothe particular purpose in View, namely either by regulating only the uantity of combustible gas streaming `t ough at one side 'of the current of gas under pressure by choosing a corresponding diameter', or in leading the combustible only at oneoi the gas outlets.

The device embodying our invention oo nsists of a rose or mouth-piece in which suiti ably arranged outlet openings are provided around the outlet for the current ,olf gas.

Any suitable mixture oil gas may bey adopted;

applicants use with advantage a combination of acetylene and oxygen.

In the accompanying drawing several .modified iorms oi construction are shown:

Figure 1 is a longitudinal section through4 the mouth piece. Fig. 2. is a face view of the mouth-piece. Fig. '3 is a cross section ot a mouth-piece with outlet openings arranged- .I in different planes. Be it known that we, EMLLEGAUTHIER l let openings of different sizes.

`under high .pressure, openings ble.

[The mouth-piece designated g in Fig. l is l.

led by tivo conduits oi which one a, leads the coiiibustiblef serving to heat the -place of.. Work, which consists of a gas mixture mixed gen under high pressure for fusing-the metal,

.iijhicli is cut through by the high pressure gas. v-Tlie oxygen leaves the mouth-piece through the opening e while the gas .mixture goes through the openings d and-is ignited. With the apparatus hitherto employed the leading o i` the combustible took place through a channel concentric with the conduits for In the form of construction shown in Fig.

and gas 'current (oxygen) are arranged in one plane. The piece of inetalsubjected to the operation of the device is heated' up o osite the outlet openings d, and it is sulgif cient to heat up the particular spot to a red heat for the purpose of' producing the subsequent action of the streani ot oxygen (perforations) in the piece oi' the metal. Ii now the! -device is moved forward on the line :z3- for instance in the direction oi-the arrow, then the perforation is continued in the line :zzand the metal cut in two.

The heat necessary for carrying out-the process is delivered by the combustible gases and partly by the iiietal itself, which latter through the combustible gas mixed with oxygen and on account of the current oi the gas under high ressure is\str0ngly heated up. The' heat li erated; by the coinbustion ot the metal diminishes the quantity of heat to be applied by the hot gases. Experience shows that the relative positions of the openings d and e is of considerable importance for the action produced,

- noty only in regard to the Wear and tear of the parts of the devicein the neighborhood of the heatedl inetal7 but-also in respect to the rapidity of' the working process, the

beauty of the cut and economy in thcconsumption of gas.

A further improvement consists in arranging the outlet for the stream of gas in a lower plane than the heating jet outlet, thatV is to say nearer tothe place of Work than that of the outlet openings for the combusti- This forni of construction is shown in Figs. 3, 5 and 6 in which the mouth-piece is provided with a projection h in which the ss. with oxygen, while `lthe other?) leads the oxyv1 the outlet openings for thecjoinbustible los one side of the oxidizing oxidizing gas outlet channel e is While the combustible mouthpiece through openings on the side toward which the ap paratus is shifted, is of importance for the practicalv operation of the apparatus.

T e evice having enlarged openings on jet is shown in Fi 4, and thearrangement is such that a shifting of the tool towards the left in the direction of the arrow on line Y-Y is intended. In this construction, accordingly, the outlet openings d2 in the working direction of the 'tool, namely on the left side of the gasonta greater diameter than those on the right side. Finally the invention can be so modified, that the outlet openings for the gas will be located only at one side of the current of oxidizing gas. 'g. 5.)

he number, 'the diameter and the position of the combustible gas openings d and the position of the oxidizing gas opening e1 in Fig. 5 can be chosen according to the properties of the particular metal dealt with of` sect1on. f
